Abstract
The invention discloses a plugging cover of a high voltage fuse. The plugging cover of the high voltage fuse comprises an upper cover component and a barrel-shaped component. The upper cover component comprises a wiring terminal and an inner thread which is arranged inside the upper cover component. The barrel-shaped component is of a hollow structure, an outer shell at the upper end of the barrel-shaped component is provided with an outer thread which is matched with the inner thread, and threaded holes are formed in the shell at the lower end of the barrel-shaped component and are used for fixing the barrel-shaped component on the high voltage fuse. According to the plugging cover of the high voltage fuse, the high voltage fuse can be placed inside the barrel-shaped component, the barrel-shaped component and the upper cover component are connected through the threads, the wiring terminal is externally connected with a wire and internally connected with the high voltage fuse, when the high voltage fuse needs to be replaced, only the upper cover component needs to be disassembled from the barrel-shaped component, due to the fact that the barrel-shaped component and the upper cover component are in threaded connection, compared with a traditional bolted connection mode, disassembling is more convenient, the threads cannot be influenced by the external environment easily, and the damage extent is greatly lowered.
Description
Technical field
The application relates to electric power infrastructure device technical field, more particularly, relates to a kind of high-tension fuse capping.
Background technology
In power engineering, the voltage transformer high voltage fuse that transformer station installs and uses is a kind of safeties, and it runs into, and the impacts such as special weather very easily cause that fuse burns, PT broken string.Therefore, just need to change for the high-tension fuse having damaged.
But the high-tension fuse two ends that existing transformer station is used are all to adopt to be screwed, through erosion by wind and rain, screw corrosion is serious, and the screw-socket of high-tension fuse very easily produces deformation, has brought very large difficulty to O&M maintainer's dismounting.And what existing high-tension fuse adopted is that split type enclosing cover is reinforced, its contained spring pressure is large, causes enclosing cover and fuse the application crimping difficulty, needs two and installs, and a people firmly makes enclosing cover and insulator connect reality, and another people installs compressing tablet and screw.Greatly affect the speed of fuse replacement.
